There has always been a lot of interest in accelerating brain function with the use of drugs and chemicals but I'm not aware of anything yet that stimulates the hippocampus to store long term memory.

Alternating current. Direct current (DC) circuits involve current flowing in one direction. In alternating current (AC) circuits, instead of a constant voltage supplied by a battery, the voltage oscillates in a sine wave pattern, varying with time as: In a household circuit, the frequency is 60 Hz. The angular frequency is related to the frequency, f, by: Vo represents the maximum voltage, which in a household circuit in North America is about 170 volts. We talk of a household voltage of 120 volts, though; this number is a kind of average value of the voltage.
